15 Facts on H2SO4 + Mn(OH)2: What, How To Balance & FAQs

by

The formation of recognizable products is the aim of a chemical reaction. Let us look at the reaction between H2SO4 and Mn(OH)2 as an illustration.

H2SO4, also known as sulphuric acid, is composed of oxygen, sulphur and hydrogen. Mn(OH)2 is a white solid, but samples quickly turn dark when exposed to air because of oxidation. It does not dissolve well in water.

Let us discuss the product formed when H2SO4 reacts with Mn(OH)2, the type of reaction, the net ionic equation and many other related topics in this article.

What is the product of H2SO4 and Mn(OH)2 ?

H2SO4 reacts with Mn(OH)2 to give manganese sulphate and water.

H2SO4 + Mn(OH)2 = MnSO4 + H2O

What type of reaction is H2SO4 + Mn(OH)2 ?

H2SO4 + Mn(OH)2 is an acid-base reaction because salt and water are produced when strong acid and weak base interact.

How to balance H2SO4 + Mn(OH)2 ?

The following steps need to be followed while balancing a chemical equation.

  • Given below is an unbalanced chemical reaction of H2SO4 and Mn(OH)2

H2SO4 + Mn(OH)2 = MnSO4 + H2O

  • Record the moles of each element on the reactant and product sides.

Moles of elements in reactant and product side
  • Now, the number of moles present on each side of the reactant and product must be equal in order to balance the chemical equation. In this case, the number of moles in each element is varied.
  • In order to make the no. of moles equal, the water present in the product side must be multiplied by 2.
  • Hence, the balanced chemical equation is H2SO4 + Mn(OH)2 = MnSO4 + 2H2O

H2SO4 + Mn(OH)2 titration

The information below will provide a general idea of the titration of H2SO4 and Mn(OH)2.

Apparatus Used

Volumetric flask, conical flask, measuring jar, wash bottle, pipette, burette, burette stand, and watch glass.

Indicator

The phenolphthalein or methyl orange indicator can be used because it is a strong acid versus weak base reaction, and its endpoint is pink to colorless.

Procedure

Standardized H2SO4 is added to the burette, and Mn(OH)2 is placed in a conical flask. Titration is then started by adding drops of H2SO4 one at a time, and an indicator is added in the middle. Titration is continued until the solution turns colorless.

It is the equivalence point; record the readings, and use the formula V1S1=V2S2 to calculate the volume of MnSO4.

H2SO4 + Mn(OH)2 net ionic equation

The net ionic equation for the reaction of H2SO4 + Mn(OH)2 is:
2OH– = + O2-

H2SO4 + Mn(OH)2 conjugate pairs

The conjugate acid-base pairs of H2SO4 + Li2O are:

H2SO4 (Conjugate base) = HSO4–
H2O (Conjugate base) = OH–

H2SO4 and Mn(OH)2 intermolecular forces

  • The intermolecular force present in H2SO4 is due to the strong electrostatic force between a proton and sulfate ions.
  • In Mn(OH)2 only covalent force is present.
  • H2SO4 shows ionic character in an aqueous medium and acts as a good dehydrating agent.

Is H2SO4 + Mn(OH)2 a buffer solution ?

H2SO4 + Mn(OH)2 is not a buffer solution due to the presence of the strong acid H2SO4.

Is H2SO4 + Mn(OH)2 a complete reaction ?

H2SO4 + Mn(OH)2 is a complete reaction since all of the reactant’s moles are completely converted and consumed by the product at equilibrium.

Is H2SO4 + Mn(OH)2 an exothermic or endothermic reaction ?

The reaction between H2SO4 and Mn(OH)2 is exothermic as the energy generated during the reaction is sufficient to carry out the entire reaction. There is no requirement for extra energy.

Is H2SO4 + Mn(OH)2 a redox reaction ?

H2SO4 + Mn(OH)2 is not a redox reaction because there is no change in the oxidation state of any element either in the reactant or product side.

Is H2SO4 + Mn(OH)2 a precipitation reaction ?

H2SO4 + Mn(OH)2 is a precipitation reaction as the reaction involves the formation of a salt.

Is H2SO4 + Mn(OH)2 reversible or irreversible reaction ?

H2SO4 + Mn(OH)2 is irreversible because the products no longer undergo backward reactions to form reactants under the same conditions.

Is H2SO4 + Mn(OH)2 displacement reaction ?

H2SO4 and Mn(OH)2 is a double displacement reaction because the sulfate ion is transferred from H2SO4 to MnSO4 and the Hydrogen ion is transferred from H2SO4 to H2O.

H2SO4 + Mn(OH)2 = MnSO4 + H2O

Conclusion

The reaction between H2SO4 and Mn(OH)2 produces a solid MnSO4 that is a light pink deliquescent color. It is a precursor to many other chemical compounds, including manganese metal.
